Hi,

I've a RPi2 with Xbian running on it.
Everything was fine until a few days ago.

The file systems on the SD card are turning Read Only after runing a few (random) time.

When I reboot the RPi2, everything is fine.
I've a USB Harddisk plugged on the RPi2 and no read only problem on it.

dmesg output :
